Description
Technical field
The present invention relates to the solar energy utilization technique field, relate in particular to a kind of solar energy air heat collector.
Background technology
At present, generally the solar energy air heat collector of Shi Yonging has two kinds of board-like and thermal-collecting tube types, board-like heat collector mainly by around have the insulation base plate that is incubated frame and the heat-collecting plate core and the glass cover-plate that are arranged on the insulation base plate constitute, the thermal-collecting tube type heat collector mainly is made of inlet, outlet pipeline and several thermal-collecting tubes of being set up in parallel.Which kind of version no matter, after air enters heat collector, all be just from heat collector, directly to discharge after once heating through one way to be sent to the place that needs hot-air, owing to be subjected to the restriction of collector structure and specification, heatable distance and time that air is flowed through in heat collector are all shorter, can not absorb heat to greatest extent, so air is through once circulation back temperature rise is less; In addition, the hot-air in this type of heat collector is that nature flows, and circulation rate is slow excessively, and system temperature also can't be regulated as required, uses mostly to be inconvenience.This shows that the thermal-arrest rate of above-mentioned air collector does not realize maximization, farthest thermal-arrest, hot.
As everyone knows, in solar energy utilization technique, an important key problem in technology is how to collect sunshine expeditiously and change it into heat energy substantially, so research and develop new and effective solar thermal collector, maximally utilising solar energy is the target that solar thermal applications area research personnel pursue all the time, and gentle high-temperature heat supply system also was a research and development direction of present solar thermal utilization during solar thermal utilization was expanded to.
Summary of the invention
The purpose of this invention is to provide a kind of air endothermic effect tortuous flow doubleeffect heating solar heat-collector air heat collectors that temperature rise is bigger, the thermal-arrest rate is higher that better, once circulates.
For achieving the above object, the present invention adopts following technical scheme: tortuous flow doubleeffect heating solar heat-collector air heat collectors, comprise the insulation base plate and be installed in the heat collector core that is incubated on the base plate, the heat collector core comprises the absorber plate that is installed on the insulation base plate, has the airtight hot-flow flue that adds between absorber plate and the insulation base plate; Above absorber plate, be provided with first horizontal admission line and horizontal outlet pipe, the below of absorber plate is provided with horizontal lower supporter, be provided with the second airtight admission line in the lower supporter, sealing is provided with and is vertical spaced thermal-collecting tube between lower supporter and the outlet pipe, and thermal-collecting tube is positioned at the top of absorber plate plate face; Add the upper/lower terminal of hot-flow flue and first, second corresponding admission line connection, the upper/lower terminal of thermal-collecting tube and corresponding outlet pipe, second admission line are communicated with; On the insulation base plate, the glass cover body that fastens the heat collector core is installed, forms enclosure space between glass cover body and the insulation base plate.
The level bending again after the lopsidedness bending of insulation base plate of the and arranged on left and right sides limit of described absorber plate, absorber plate post and fix with the insulation base plate by its horizontal bending part and are connected; The upper/lower terminal of absorber plate is the blind end that adds hot-flow flue, is equipped with the gas connection pipe road at the transverse center position of upper and lower blind end, adds hot-flow flue by gas connection pipe road and first, second corresponding admission line connection.
The position of left-right symmetry center line outwards convexes to form arched ribs with respect to the insulation base plate on the absorber plate.
The absorber plate plate body makes progress and has multilayer gradual change selectivity on the surface of Chaoyang and inhale film.
Described thermal-collecting tube comprises glass tube and the endothermic tube that is sleeved in the glass tube, and the open at both ends of endothermic tube, the corresponding end of also stretching out glass tube respectively are vacuum interlayer between endothermic tube and the glass tube, and the surface of endothermic tube has coating for selective absorption; The two ends that thermal-collecting tube stretches out by endothermic tube are inserted on outlet pipe and the lower supporter, and thermal-collecting tube is communicated with second admission line in outlet pipe, the lower supporter by endothermic tube.
Described endothermic tube is copper pipe or stainless steel tube.Described glass tube is the high-boron-silicon glass pipe.The connecting portion of thermal-collecting tube and outlet pipe and lower supporter seals by seal.
The outlet of described outlet pipe is provided with the pump housing.
The present invention places glass cover body and the confined space of insulation between the base plate with the heat collector core, and the glass cover body can make the loss of system thermal farthest reduce, and is subjected to the influence of cool ambient air little, makes the residing temperature environment of heat collector core relatively stable.Air is entered by the import of first admission line and adds hot-flow flue, in the air channel, carry out the heating first time, carry out the heating second time by dividing behind the second admission line baffling to each thermal-collecting tube then, the gas after the heating is discharged from outlet pipe and is delivered to the place that needs hot-air.Because the heat collector core has been realized the economic benefits and social benefits heating of the absorber plate and the thermal-collecting tube of air, make the heating distance nearly double, the heating distance, heat time heating time is long, so improved heat absorption efficiency effectively, strengthened endothermic effect, made a circulating temperature rising of air faster, collecting efficiency is higher.
In the whole device, lower supporter is also double does that second admission line uses, outlet pipe is also doublely done stent support, connect thermal-collecting tube, makes compact overall structure, succinct.The arched ribs of absorber plate plate body can also increase the intensity of plate body simultaneously in order to increase the caliber of inlet, outlet connecting pipe; Multilayer gradual change selectivity on the absorber plate is inhaled film and can be reached more than 93% the absorptivity of solar energy, and the thermal-arrest rate is higher, and thermal emissivity rate is lower than 6%, makes heat loss littler; And this heat absorption overlay film layer is difficult for wearing out, coming off, and significantly improved the service life of absorber plate.
Thermal-collecting tube adopts straight-through type vacuum sandwich, and skin is the high-boron-silicon glass pipe, and endothermic tube is selected the copper pipe of high thermal conductivity coefficient for use, so the light transmission of thermal-collecting tube is good, the thermal efficiency is high and thermal losses is low; Internal layer endothermic tube plating coating for selective absorption can improve heat absorption efficiency effectively, and it is faster that temperature is risen.The two ends correspondence of endothermic tube is stretched out outside the glass tube two ends, is beneficial to the sealing assembling of thermal-collecting tube and lower supporter and outlet pipe.
The pump housing that disposes in the device is used to quicken the flow velocity of air, so that the improved efficiency of whole device is faster, and can realize control to system temperature by the speed of the control pump housing, uses more convenient.Adopt seal can further reduce heat loss.
